Yes.
a test for a function is the vertical line test, so think about drawing a vertical line on top of this picture. if at any point the line is touching the graph more than once, it is not a function. this graph passes the vertical line test
2^31
use the rule that states the product of the same base with different powers you add them
(a^n) times (a^m) = a^(n+m)
no because the three is negative so the -3 is less than c.
Hope this helps.
